The results showed that leaf epidermal cells were polygonous or irregular in shape. Stomatal complexes only present on abaxial epidermis and the stomata was paracytic type. There were five types of anticlinal walls of abaxial and adaxial cells (straight, rounded, undulated, sinuous, straight-curved). Trichomes on abaxial epidermis exist or not. Ornamention types of periclinal walls could be divided into punctuate, smooth and striate. Ornamention of periclinal walls on inner side of abaxial epidermal cells varied widely (irregular, smooth, roughly reticular, micro hairy, granular, scaly).

结果表明：润楠属植物叶表皮细胞形状为多边形或不规则形，气孔复合体均为平列型且仅分布在下表皮；上下表皮细胞的垂周壁式样有5种类型：平直、圆滑、浅波、波状、平直-弓形；下表皮毛被有或无；上表皮平周壁纹饰类型有：点状、平滑、条纹；下表皮内面平周壁纹饰类型有：不规则、平滑、粗糙网状、微毛状、颗粒状、鳞片状。

Objective:The study mainly utilize the raphanus which is a edible Chinese officinal herb and has little side-effect, easily accepted, steadly effect, and so on, to exploit its pharmacological value on gastrointestinal motility. By observing the effects of the crude extract of radishon the electrogastrogram,gastric emptying and small bowel peristalsis activity of the rats in vivo ,the effects of Ecr on gastrointestinal motility could be manifested. Furthermore, the contrast study about the effects of gastrointestinal motility was also observed among Ecr domperidone and prepulsid. The mechanism was explored by observing Ecr on the expression of Fos protein of the dorsal vagal complex.

目的：本研究主要利用十字花科萝卜属植物白萝卜作为食源性中药，具有副作用少、易被接受、作用稳定等特点，通过白萝卜提取物(The crude extract of radish，Ecr)对在体大鼠胃排空、肠推进、胃电活动的观察，并与经典的促胃肠动力药物进行对比观察，研究提取物对大鼠胃肠动力的作用；进一步通过研究提取物对大鼠中枢支配胃运动的迷走复合体(Dorsal vagal complex，DVC)中Fos蛋白表达的影响，从而反映DVC被激活的情况，来探讨白萝卜提取物促进胃肠动力的机制，从而为其在胃肠动力相关的功能性疾病的治疗上的应用提供实验基础和理论依据。
